Structural and Physical Properties of “Field-Edited” Iridates

POSTER

Abstract

A great deal of theoretical work addressing exotic states for iridates has thus far met very limited experimental confirmation. The conspicuous discrepancies are due chiefly to the extreme susceptibility to structural distortions inherent in these materials. To fundamentally address this challenge, we have structurally “edited” these materials (borrowing the phrase “genome editing”) via application of magnetic field during single-crystal growth. Our results have demonstrated that the “field-edited” single crystals not only are much less distorted but also exhibit some long-sought phenomena absent in the same materials grown without a magnetic field. We present and discuss these results along with comparisons drawn from other relevant systems.
